Does It Matter If a Fundraising Database Supplier Doesn't Understand Fundraising?

The more I work on fundraising software procurement and implementation projects, the more I ask this question: How much does the supplier's experience of fundraising matter?

For years, this hasn't been such a relevant question, at least when purchasing packages as opposed to bespoke systems, because most new fundraising database systems were supplied by companies who either specialized in the sector or who at least had a dedicated department who did so.
